Bullish Case: Known: CPRT $27.28 with heavy put volume and mild IV backwardation (front-end fear higher than later). The CPRT IV surface shows stronger downside skew (strikes <~27 priced richer), while SPY’s surface is smoother/lower—more idiosyncratic than broad-market stress. The historical return surface’s brightest regions cluster around modest gains, supporting mean reversion. After the Jul 31 CEO transition, a left-tail IV compression could enable a snapback toward ~$30–33.

Bearish Case: Known: put-heavy flow plus persistently elevated left-wing IV on the CPRT volatility surface suggests downside tail pricing remains active. The return surface assigns non-trivial likelihood to -10% to -25% over shorter holds, even if deep losses are less frequent. The CPRT term structure backwardation implies near-term fear may not clear quickly. Calibration: your prior “drift lower” scenarios were directionally right (price below your 30–33/28–30 bands), while the 40+ rebound didn’t materialize—keeping auction/insurance headwinds post–Jul 31 plausible.

Potential Outcomes:

1. 40% Rangebound $26.5–$30.0; falsifiable: closes stay in-band and front-end IV trends down after Jul 31.
2. 25% Drift to $24.5–$26.5; falsifiable: weekly close < $26 and left-wing put IV rises.
3. 25% Rebound to $30.5–$33.5; falsifiable: holds > $29.5 after Jul 31 and downside IV compresses.
4. 10% Vol shock < $24; falsifiable: short-dated put IV >45% plus SPY risk-off.

Oracle (conditional): CPRT<26 & IV>40 → long-convexity; CPRT>30 & IV<38 → call-spread.
